Black Guan

Round-headed diving duck. Males have black breast, medium gray back, white sides, and yellow eye. Head appears black with a greenish sheen in good lighting, never purplish. Females are brown overall, grayer on body in winter, with white patch at base of bill and yellow eye. Very similar to Lesser Scaup; note smoothly rounded head without tall peak, puffier cheeks, more extensive white stripe on wing in flight, and larger, broader bill. Can be similar to immature male and female Tufted Duck, but note smoothly rounded head and more extensive white bill base patch in females. Often in flocks with other Aythya ducks. Tends to prefer saltwater bays and coves, but also found in freshwater.

Typically dull mid-sized greenbul with a long bill and tail. There is geographical variation, with the western birds more yellowish below, and the eastern birds more whitish. Usually shows a distinctive pale eye-ring. Found in the thick undergrowth and mid-story of forest at middle and high elevations, usually in small groups. The call starts with slow and chatty notes, then accelerates into a grating, up-and-down series. Somewhat similar to Gray-olive Greenbul, but larger, with a darker bill and legs and usually some yellowish tones on the underparts. Similar to brownbuls, but more olive-green on the back and yellowish below.

A large, heavy-billed finch. Male is black above and yellow below with white streaks and spots on the wings. Female is patchy black above and yellow below with heavy black streaking all over the underparts. Male closely resembles White-winged Grosbeak, but Spot-winged has a yellow (not black) chest, and smaller and more numerous spots on the wings. Inhabits submontane areas, particularly in mixed forests. Often seen in pairs or small flocks, but may gather in large flocks near fruiting trees. Call is a mellow descending note.
